Given a very specific intonation and given a specific context, a pre-existing conversation, the second one could mean the first one, it would emphasize that Tuesday is still the subject, just shuffled around.

In case of п'ятниця it's "Вчора була п'ятниця", so the verb corresponds to the day of the week, not "yesterday", so... Yesterday is not a subject.... But the two sentences still do sound different... But... * leaves tired and confused *
